label data "State cluster identifier (1-48) for each observation"
note _dta: Integer cluster id 1-48; each state appears exactly 12 times (one per first-differenced year). Aligns row-for-row with levitt_linear, levitt_partialled, and the three control matrices.
note state: Integer id of the U.S. state for an observation; the clustering variable for HC1 standard errors.. Construction: From the replication archive's State.mat (Dstate); 1..48, each state appears 12 times.. Units: integer 1-48. Source: Donohue & Levitt (2001) / BCH (2014) panel

note _dta: Raw first differences of the 1985-1997 level panel. Three (Dy, Dx) pairs, one per outcome: v=violent, p=property, m=murder. Used for the no-controls Donohue-Levitt baseline before any year-FE partialling.
